NEW YORK (ABC) -- New York City subways and buses are running, but Amtrak canceled service north out of New York City. Long Island Rail Road, Metro North and New Jersey Transit were either delayed or suspending some service.

NYC SUBWAYS
The MTA has advised riders that the storm may require suspension of some portions of the region's subway, bus and commuter train operations.

The MTA has prepped and deployed its fleet of snow and ice-busting equipment to keep outdoor tracks, switches and the electrified third rail clear of snow and ice.

The MTA has canceled all weekend work.

MTA personnel have been deployed to keep subway stairways clear of snow and salted to melt ice.

Depending on conditions, routes may be canceled, fewer buses will run and some bus stops will be skipped.

LIRR
Customers are advised, if snow accumulations exceed 10-13 inches, we will temporarily suspend service to ensure the safety of our customers and employees, and to allow snow-fighting equipment to clear snow from the track and third rail.

NJ TRANSIT
NJ_TRANSIT is suspending service on the Morris Essex, Montclair Boonton and Midtown Direct lines from 8pm Friday through Saturday

Bus Service: NJ TRANSIT bus service in northern and central New Jersey (all routes north of I-195) will be suspended as of 8 p.m. This includes all routes that serve Port Authority Bus Terminal and George Washington Bridge Bus Terminal, all routes that operate via U.S. Route 9, and all northern local bus routes.

METRO-NORTH
Because of the accelerating severity of the storm as well as projected snowfall accumulations of more than a foot, Metro-North Railroad will begin a suspension of train service on the Hudson, Harlem and New Haven Lines at approximately 10 p.m. This service suspension will continue until further notice.

With the significant increase in snowfall and high winds, the risk of a train becoming disabled with customers on board also increases significantly. Therefore, it is important to stop service at this time to ensure customer safety and to allow Metro-North employees to conduct aggressive snow fighting operations to keep the right of way as clear as possible. Road conditions have also deteriorated, with many road closures in Metro-North's service territory.

In addition, Grand Central Terminal will close after the last trains arrive, approximately midnight.

AMTRAK
Amtrak has suspended service in New York and New England.

Connecting service between Albany, N.Y., and Boston to the Lakeshore Limited also is canceled.

CT TRANSITGovernor Daniel P. Malloy this afternoon announced that CT TRANSIT bus service will begin shutting down service at 4PM today, and all buses will stop running by 6PM. This shut down will be in effect for the entire state until further notice.
